Patent ES-333300-A1 (ES)
Title: Servicing arrangement for spinning machines
IPC: D01H4/08
Filed: 1966-11-12
Abstract: So that the units of a break-spinning frame can be stopped individually for maintenance, cleaning or the repair of a broken end, each unit comprises two housings, one for the spinning chamber, and one for the combing roller and the outlet through which the spun yarn is withdrawn, the housings being rotatably mounted about parallel axes so that they may be swung apart. The housing 17, Fig. 4 for the combing roller 5 and the yarn outlet 41 which also carries an inlet passage 5 for the sliver, a feed roller, and a separator plate 38, is rotatably mounted on a tube 8 common to all the housings. The housing 14 for the spinning chamber is hinged to the frame at 13, its weight and that of the associated driving- pulley 15 causing the pulley to engage a braking-surface 21 when the housings are separated. The tilt of the housing 17 is limited by a spring-catch 16 mounted thereon which engages the housing 14 and helps to tilt it. When the housing 17 is in tilted position, the drive roller 48 of the combining roller is separated from its drive belt 4 and the drive of the feed roller is disconnected in a manner to be described below. When the housings are to be restored to spinning position, the housing 17 is swung towards the housing 14 a spring-urged pin 49 on the former engaging the housing 14 and tilting it back to working position, where the pulley 15 moves off the braking surface to engage its drive belt 2 before the separator plate 38 enters the spinning chamber. The two housings are held in working position by a catch 57 - 18. The feed roller is driven by gearing from a gear 25 which engages a gear on a drive shaft 6 common to all the units which passes through the tube 8. The gear 25 is one part of a clutch with which the other is held in driving engagement by a spring, but which is withdrawn when a solenoid is energized. The solenoid is in circuit with a feeler, the circuit being open as long as a thread engages a feeler 42 near the thread outlet 41. When the thread breaks or is absent, the feeler closes the circuit to disengage the clutch and stop the feed roller at the same time a signal lamp is switched on. The lamp is disposed within the upper part of the housing 17 the cover of which includes a translucent plate 54 so that it can be seen when the lamp is switched on. A branch circuit across the feeler terminals includes a capacitor and a resistance to prevent sparking, the resistor reducing the voltage across the lamp terminals. The catch 57, 18 can be released manually by a handle 58 to separate the housings and separate the pulleys 15, 48 from their drive belts and move pulley 15 against the braking- surface 21. By thus bringing the spinning chamber to a stop, the delivery of thread is interrupted and the feeler operates to separate the clutch and stop the feed roller.

The centrifuge also comprises a disc 18 with projections 17 that engage apertures in basket 20 and cavities 16 in plate-shaped member 12, and a friction disc 21.

Patent ES-355539-A1 (ES)
Title: Method of optimum operating a sedimentation apparatus and a device for carrying out the method
IPC: B01D21/00
Filed: 1968-06-27
Abstract: Liquid containing suspended solids enters tank 5 at inlet 1, clarified liquid overflows at 2 and concentrated sludge is pumped out at 3, the inlet or sludge outlet flow being so controlled as to optimise separation, the sludge being then at its most concentrated consistent with a clear liquid effluent. Under these conditions a sharp level 4 is observed where solids concentration varies abruptly, and the flow is controlled to hold this level 4 between the mouths of two tubes 6 which are filled with clarified liquid and lead to an oil-filled inverted U-tube serving as a differential pressure gauge. The level of the oil-liquid interface is monitored by photocell 8 and used to control the sludge pump 9 automatically. Alternatively, the level is merely observed and control is manual. Sedimentation is assisted by vibrations applied directly to the liquid, at 10, or to the tank wall. The wide part of the righthand leg of the U-tube magnifies the interface movement in the left-hand leg as differential pressures vary. Fig. 5 shows a simple settling tank, but the invention also applies to a tank divided by inclined baffles into compartments which operate as parallel settling zones (Fig. 4, not shown).

Title: Device for trimming flash from metal which has been worked with a machining torch
IPC: B23K7/00
Filed: 1968-11-21
Abstract: Flash produced at the start of a machining pass on a metal workpiece at an edge 18 transverse to the sides 6, 8 of the pass, is removed by blowing oxygen on to the flash before it has cooled to the point where it can no longer burn in oxygen without preheating. A torch nozzle is shown at 2 at the beginning of a scarfing operation on a steel slab and at 4 when it has effected the pass. The flush formed at the edge 18 of the scarfing pass during the starting operation is removed by oxygen nozzles 10, 12, 14, 16 fixed to the torch support and inclined at 10- 70 degrees to the workpiece surface. The flash at the side 8 of the pass is removed by oxygen nozzles 20, 22, 24 inclined at 30-60 degrees to the workpiece surface and 30-50 degrees with the direction 26. Nozzles 28, 30 may be arranged on the side 6 of the pass inclined at 20-90 degrees with the workpiece surface and 0-70 degrees with direction 26. The apparatus may be used to cut a blind hole at the end of a bar for producing seamless tubes.
